refactor: Delete 7 redundant tests from main_test.go (3x speedup)

Problem: main_test.go was testing deprecated legacy path after FlushManager
refactoring (bd-52), duplicating coverage from flush_manager_test.go.

Solution: Delete redundant tests, keep only unique integration tests.

Changes:
- Deleted 7 tests (407 lines) covered by flush_manager_test.go:
  * TestAutoFlushDirtyMarking → TestFlushManagerMarkDirtyTriggersFlush
  * TestAutoFlushDisabled → TestFlushManagerDisabledDoesNotFlush
  * TestAutoFlushDebounce (already skipped, obsolete)
  * TestAutoFlushClearState (tested implicitly in export/sync)
  * TestAutoFlushConcurrency → TestFlushManagerConcurrentMarkDirty
  * TestAutoFlushStoreInactive → TestPerformFlushStoreInactive
  * TestAutoFlushErrorHandling → TestPerformFlushErrorHandling

- Kept 2 unique integration tests:
  * TestAutoFlushOnExit (tests PersistentPostRun)
  * TestAutoFlushJSONLContent (tests actual JSONL output)

- Updated clearAutoFlushState() to no-op when FlushManager exists

Results:
- Before: 18 tests, 1079 lines, ~15-20s
- After: 11 tests, 672 lines, ~5-7s
- Speedup: ~3x faster
- All tests passing ✅

Files:
- cmd/bd/main_test.go: Deleted 7 tests, removed unused imports
- cmd/bd/autoflush.go: Updated clearAutoFlushState()
- docs/MAIN_TEST_REFACTOR_NOTES.md: Documented solution
- docs/MAIN_TEST_CLEANUP_PLAN.md: Created detailed plan
